What’s the point of using a feature loaded phone when you can’t even update its Android operating system?
OnePlus owners have something to be delighted about as the year comes to an end: OnePlus is rolling out the Android Oreo update for most of its phone before the year wraps up.
OnePlus 3/3T and OnePlus 5 or 5T have already received the 8.0 stable update. For OnePlus 5, users were promised OxygenOS-based Android Oreo beta before December, and it happened. Another promise that the company made was to release a stable OTA during early 2018. However, it appears that OnePlus has somewhat switched their timeline to give OnePlus 5 owners a merry Christmas and happy new year’s present: OxygenOS 5.0. The update based on stable Android Oreo now officially gets updated to the OnePlus 5.
OnePlus Community Forums officially announced OxygenOS 5.0 update on December 24, 2017. The incremental update’s officially available in Hong Kong, Canada, Finland, and Germany with it widely making it to other countries later on.
If you are keen on updating or installing it right away, you can check the link OnePlus is offering (download link for OTA package).
With Android 8.0 Oreo update, you can enjoy picture-in-picture mode, smart text selection, Autofill API, notification channels, etc. It also gets you native support for custom themes via Substratum along with numerous changes like mechanical changes like stricter background app limitations.
OnePlus won’t be offering Project Treble support because there is not dedicated vendor partition available. Nevertheless, you can anticipate December security patch.
Although, there isn’t any concrete information on when the Android 8.0 Oreo update will be available for OnePlus 5T but given the changes that happened this year, you might not have to wait for too long either.
Android 8.1 may become available after some time on OnePlus 3/3T and OnePlus 5/5T but users can’t find anything noticeable on the maintenance list either.
If you successfully want to update your OnePlus 5 to Android 8.0, ensure that you employed a Germany/Canada/ Finland/Hong Kong VPN to download the update via built-in OTA client.
Or you can check the OnePlus servers to get your individual download of OTA package. Flashing it to your OnePlus through TWRP should do the deed.
And, if you happen to have patience, wait for a while until the wider roll out becomes available.
